Stormy Daniels' lawyer is now involved in the battle over Brett Kavanaugh's Supreme Court nomination—and he says he has a client with "credible information" to support some shocking allegations.

In an email to the Senate Judiciary Committee, Michael Avenatti said he was aware "of significant evidence" of house parties in the early '80s during which Kavanaugh "and others would participate in the targeting of women with alcohol/drugs in order to allow a 'train' of men to subsequently gang rape them," the New York Daily News reports.

"Multiple witnesses." Avenatti tells Politico that he is representing "multiple witnesses" who can back up allegations of misconduct involving Kavanaugh and his friend Mike Judge.

He says the witnesses "went to schools in the same general areas" as Georgetown Prep, which Kavanaugh and Judge attended. Avenatti says the allegations are "not out of character" from the behavior described by Christine Blasey Ford, who says Kavanaugh, with Judge present, sexually assaulted her at a house party in 1982.

Feinstein calls for delay.

The top Democrat on the Senate Judiciary Committee called Sunday for an "immediate postponement" of proceedings relating to Kavanaugh's nomination, the Washington Post reports. Sen.

Dianne Feinstein called for the FBI to investigate the allegations from Deborah Ramirez, the Yale classmate whose account was published in the New Yorker. The committee had scheduled a hearing Thursday to address Ford's allegations.

"FFFFFFFourth of July." Brett Kavanaugh must also be asked about this entry in his yearbook: 'FFFFFFFourth of July,'" Avenatti tweeted late Sunday. "We believe that this stands for: Find them, French them, Feel them, Finger them, F*ck them, Forget them.

As well as the term 'Devil's Triangle.'"

Republicans respond. Republicans on the Judiciary Committee say they will investigate Ramirez's allegations, though there has been no response yet on Avenatti's, the AP reports. Committee spokesman Taylor Foy, however, complained that Democrats "actively withheld information" from Republicans.

Kavanaugh's calendars. The New York Times reports that as part of his defense, Kavanaugh plans to give the Judiciary Committee calendars from the summer of 1982 that show he spent much of the summer out of town. They list activities including movie outings and college interviews, along with some parties. Kavanaugh also listed some parties and the names of friends he went with, but none that match Ford's account.
